Cross-linked chitosan/waste mussel shell (C/WMS) and chitosan/waste mussel shell/waste active sludge char (C/WMS/WASC) composites were prepared from waste mussel shell, waste active sludge (WAS), and chitosan, and cross-linked with glutaraldehyde. The quantities of chitosan, WMS, and WASC used for the C/WMS and C/WMS/WASC composites were 1:1 and 1:0.5:0.

The surface morphology and elemental composition of chitosan/WASC beads were characterized using Scanning Electron Microscopy (SEM). Adsorption isotherms of Cu(II) ions on adsorbents were correlated with the Langmuir and Freundlich models, and the data fitted better to the Freundlich isotherm model.

- A new series of liquid rare earth chlorometallate complexes featuring the alkyl-phosphonium cation [P666 14](+) has been created and studied in detail.
- EXAFS analysis showed that the [LnCl6](3-) ion is the main form in these liquids for elements like Nd, Eu, and Dy.
- The luminescence properties revealed visible light emissions for Tb, Eu, Pr, and Sm, plus near-infrared emissions for Nd and Er, with effective magnetic moments measured for several rare earth samples.
